Special Issue Information

Dear Colleagues,

Fire safety arouses increasing concern due to its versatility and the destructiveness of fire. The application of flame-retardant materials can significantly reduce the occurrence of fire hazards. Lately, considerable efforts have been dedicated to the construction of flame-retardant materials including plastics, rubbers, fabrics, coatings and adhesives. This Special Issue of Polymers aims to collectively disseminate state-of-the-art research concerning the challenges and innovations in flame-retardant polymeric materials, based on the scientific and technological understanding of fire-safe conceptualization, fire-suppression mechanisms, and fire-protection applications.

The topics of interest include but are not limited to:

  • Phosphorous-based fire retardants;
  • Nano-structured fire retardants;
  • Fire assessments;
  • Fire-retardant modes of action;
  • Ignition behaviors;
  • Smoke suppression;
  • Fire simulation;
  • Fire reaction;
  • Fire toxicity;
  • Fire-retardant composites;
  • Multifunctional fire-retardant polymers;
  • Fire protection of construction materials;
  • Functional fire-safe road pavement materials;
  • Fire-retardant fabrics;
  • Fire-resistant coatings;
  • Fire-retardant phase-change materials;
  • Fire-retardant battery materials;
  • Fire-sensing coatings and structures;
  • Bio-based intrinsic flame-retardant polymers;
  • Bio-based fire retardants;
  • Fire-retardant fiber-reinforced polymer composites;
  • Fire safety of tunnels;
  • Fire safety of coal mines;
  • Fire protection of woods.

This article investigates the effects of combining a novel protic ionic liquid-based fire retardant (FR) with alkalized hemp fiber. A pivotal importance of this study refers to the hydrophilic properties and limits regarding poor thermal resistance of green composites where standard guidelines for fire risks are crucial. Although it is well-studied that alkalization is essential for green composite’s moisture and mechanical durability, research on the flammability of such a combined treatment for natural fiber-reinforced biopolymer composites is lacking. The alkaline treatment used in the current study follows a process already studied as optimal, particularly for the selected hemp fiber. The fire performance was examined using a bench scale approach based on self and piloted ignition from cone calorimeter tests. The result from the Fourier-transform infrared analysis of the hemp fiber confirms phosphorylation following the fire-retardant treatment, which was visible from the morphological examination with scanning electron microscope. The presence of FR in the composites led to impactful moisture sorption. However, the FR composites demonstrated an enhanced response to fire, indicating potential use as a Class B standard for building construction, and hazard level 3 (HL3) classification as an interior material in vehicles, provided the problem of high emission of smoke is mitigated.

In the present review, using an integrated approach based on the experimental and theoretical study of the processes of thermal decomposition and combustion of practically important polymers, such as polymethyl methacrylate, polyethylene, and glass-fiber-reinforced epoxy resin, the features of the mechanism for reducing the combustibility of these materials with phosphorus-containing flame-retardants (FR), as well as graphene, are identified. A set of original experimental methods was developed and applied that make it possible to study the kinetics of thermal decomposition and the thermal and chemical structure of the flames of the studied materials, including those with FR additives, as well as to measure the flame propagation velocity, the mass burning rate, and the heat fluxes from the flame on the surface of a material. Numerical models were developed and tested to describe the key parameters of the flames of the studied polymeric materials. An analysis of the experimental and numerical simulation data presented showed that the main effect of phosphorus-containing fire-retardants on reducing the combustibility of these materials is associated with the inhibition of combustion processes in the gas phase, and the effect of adding graphene manifests itself in both gas and condensed phases.
